Fire Marshal Mark Mulliner said the first fire occurred in the Rosedale Griffin Park area around 5 p.m. to a building which had been vacant for seven years. The second fire occurred on 9th street around 9 p.m. and did not do a great deal of damage.

Mulliner could not confirm if the two fires were related to the previous seven fires reported in the past two weeks, but he said authorities were investigating the possible connection.

No injuries were reported in Monday's fires.

Officials are asking anyone who notices someone entering a vacant building or anyone with information on these fires to call the Port Arthur Police Department at (409) 983-8600.
